From AirHistory.net:

Built by Derek Dyer from plans for a Fisher R-80, which is an 80% scale Tiger Moth. The design has been modified to resemble a Waco UMF7 with a Rotec radial engine up front in a blister cowling and a reprofiled fuselage and fin. If you're wondering, the aircraft's name Simulata Vetera means "Fake Antique".
